The Joint Strategic Needs Assessment (JSNA) is a systematic review of the health and wellbeing needs of Lincolnshire's population. It identifies priorities and informs the Joint Health and Wellbeing Strategy. Local voluntary and community sector (VCS) organizations can influence the JSNA process by identifying needs, gaps in services, and effective interventions. They can also facilitate engagement with underrepresented community groups. The VCS plays an important role in shaping local health priorities and future service planning through the JSNA.
